How Do Pirometers Work


If you are wondering what a pirometer is, it’s a remote-sensing thermometer that has been designed to measure distant objects’ temperatures; typically, those with a higher range where distance may be necessary.

Fortunately for those who are interested in learning more, we’ve got all the information you need to better understand how these devices work and how you could make the most out of using a pirometer for your project.

So, what does a pyrometer do?

Simply put, a pirometer is one of the most effective tools for pyrometry (also sometimes referred to as radiometry). If you want to accurately determine high temperatures from a distance with ease, you’re likely to find that a pirometer will be one of the best devices available.

Also known as a pyrometer, this tool has taken many forms throughout history, and it’s safe to say that the modern era is one of the best times to make use of these kinds of tools in terms of accuracy, efficiency, and even safety.

In today’s world, these tools work by measuring the amount of thermal radiation emitted from a surface to determine its temperature (and can often do so with ease, in a matter of seconds). This is one of the main reasons why they can be so useful for a wide variety of different industries.

What is the range of a pyrometer?

Optical pyrometers typically measure temperatures from 700°C to 4,000°C. To determine the photometric brightness of a heated object as accurately as possible, an incandescent tungsten filament inside the device is often used as a basic source of comparison. Essentially, the operator will adjust the filament’s current, changing its color until it’s the same as the object being measured.

Not all pirometers work like this, though. Some instead keep a constant current within the filament and instead use an energy-absorbing wedge within the device, with the temperature of the object in question being determined by the amount of energy absorbed.

While the temperature range of a particular pyrometer can vary from one device to another, you can often expect something along these lines.

On quality pirometers, accuracy is often a similar matter. The temperature will usually be measured within 1 to 2% of the total range, which generally gives you a clearer view of what to expect. Much like the point made on distance, the amount can vary based on the pyrometer itself, so it can often be worth checking the specs.

Where can you get a good quality pirometer?
